“…There are several factors that can regulate the belowground biomass in mangrove forests, and consequently, the carbon stock associated with it. These factors include the position of the sampling area in relation to the water body, i.e., the flood tide frequency that the forest is subjected to, and the position in relation to the continent, i.e., if the forest is located in a more sheltered estuarine environment or in an open area with a higher marine influence (Sherman et al 2003, Donato et al 2011.…”

Studies on belowground roots biomass have increasingly reported the importance of the contribution of this compartment in carbon stock maintenance in mangrove forests. To date, there are no estimates of this contribution in Brazilian mangrove forests, although the country has the second largest area of mangroves worldwide. For this study, trenches dug in fringing forests in Guaratiba State Biological Reserve (Rio de Janeiro, Brazil) were used to evaluate the contribution of the different classes of roots and the vertical stratification of carbon stock. The total carbon stock average in belowground roots biomass in these forests was 104.41 ± 20.73 tC.ha . From that, an average of 84.13 ± 21.34 tC.ha −1 corresponded to the carbon stock only in fine roots, which have diameters smaller than 5 mm and are responsible for over 80% of the total belowground biomass. Most of the belowground carbon stock is concentrated in the first 40 cm below the surface (about 70%). The root:shoot ratio in this study is 1.14. These estimates demonstrate that the belowground roots biomass significantly contributes, more than 50%, to the carbon stock in mangrove forests. And the mangrove root biomass can be greater than that of other Brazilian ecosystems.

“…Compared to worldwide above-ground biomass data (as a proxy of carbon storage), mangroves in the Atrato River delta represent a significantly high reservoir, but Eastern Coast mangroves lay below the average (Tables 2 and 3; [48,49]). Therefore, conservation efforts should prevent clearing mangroves in the Atrato River delta in order to avoid releasing significant amounts of carbon to the atmosphere and to the ocean, thus negatively impacting the Gulf 's budget.…”

Ecosystem-Wide Impacts of Deforestation in Mangroves: The Urabá Gulf (Colombian Caribbean) Case Study

et al. 2012

Mangroves are ecologically important and extensive in the Neotropics, but they are visibly threatened by selective logging and conversion to pastures in the Southern Caribbean. The objective of this paper was to summarize the impacts of both threats on forest structure, species composition, aboveground biomass and carbon reservoir, species introgressions, and benthic fauna populations by collating past and current data and by using an interdisciplinary approach in the Urabá Gulf (Colombia) as a case study. Mangroves in the Eastern Coast have been decimated and have produced unskewed tree-diameter (DBH) distributions due to the overexploitation of Rhizophora mangle for poles (DBH range: 7-17 cm) and of Avicennia germinans for planks and pilings (DBH > 40 cm). Selective logging increased the importance value of the light-tolerant white mangrove Laguncularia racemosa, also increasing biomass and carbon storage in this species, thus offsetting reductions in other species. Introgressions (cryptic ecological degradation) by L. racemosa and Acrostichum aureum (mangrove fern) and low densities of otherwise dominant detritivore snails (Neritina virginea) were observed in periurban basin mangroves. Finally, basin mangroves were more threatened than fringing mangroves due to their proximity to expanding pastures, villages, and a coastal city.

“…On a global scale, temperature serves as the main factor affecting latitudinal patterns of biomass and productivity (Komiyama et al 2008, Alongi 2009). On a landscape scale, the patterns of mangrove distribution formed in response to chemical, physical and biological factors that have been previously documented within a single estuary (Sherman et al 2003, Ewe et al 2006, Alongi 2011. These factors and their relationship to forest stands have been studied to quantify spatial patterns of biomass and productivity along a geomorphological gradient.…”

“…In addition to the responses of individual trees to abiotic factors in the environment, competition within and between species also interacts with stand structure and species composition as parts of stand dynamics (Ball 2002, Clarke 2004, Rajkaran and Adamas 2012. Sherman et al (2003) and Ewe et al (2006) studied biomass, growth and productivity in association with the environmental conditions, such as salinity and nutrient status, in relation to species composition and stand structure. However, few studies address the production of biomass in relation to stand dynamics (Alongi 2011).…”

In this study, we examined the standing aboveground biomass, biomass growth, litterfall and tree species population dynamics of mangrove forest along the Nakara River, Iriomote Island, southwestern Japan, to explain the spatial patterns of stand structure and aboveground net primary production in reference to the stand dynamics of mangrove tree species along the river. The entire aboveground biomass of the mangrove forest did not vary with topographic position at the stand level, while three mangrove species showed different distributional patterns along the river. Although Bruguiera gymnorrhiza was generally dominant, Rhizophora stylosa codominated in the downstream areas. Kandelia obovata occurred only at the river＇s edge in the downstream area. The observed spatial patterns of aboveground productivity of each species depended mostly on their biomass. The distribution patterns of the mangrove tree species were based on parameters of their population dynamics, such as growth, recruitment and mortality. The effects of disturbance, especially the effects of typhoons, on the forest dynamics were prominent in this study period. The results of the study suggest that the spatial pattern of species distribution and productivity could be largely affected by the typhoon disturbances.
